摘要：A device for spreading active agents comprising: a boom, which is arrangedpivotably about a rotation axis; a sensor arrangement for the detection of an angular
velocity of the boom about the rotation axis; a sensor for the detection of an angularposition of the boom; a control unit processing output signals from the sensor; and anactuator, acting on the present angular position of the boom based on control signalsfrom the control unit. For the determination of an angular position of the boom, thecontrol unit calculates an angular position of the boom in relation to a reference planeby integration of the angular velocity and merges the angular position calculated bymeans of the angular velocity, with the detected angular position to determine thepresent angular position of the boom to return the boom to a desired angular position.
